All,
I'm having trouble using blockMesh for a simple axisymetric geometry. I have collapsed two edges per User Guide 5.3.3. I also rotated the geometry to straddle the XY plane. I am unable to generate a single cell thickness as shown in the image. Please note the angle here is set to 45 degrees for easy viewing, the issue shows up when a small angle is used (<5 degrees).

I am able to create an axisymmetric mesh using the Main ContribEample. However, my geometry should be along X and I prefer the vertex numbering from the user manual.

Where am I going wrong here? I am obviously missing something important when collapsing edges for an axisymmetric blockMesh.

Thanks!
